Abstract

The two-dimensional flow of a stream past a simple wedge partly immersed in water is investigated by linearized theory. The results are expressed in terms of a non-dimensional speed V = U($\rho \alpha $/gL)$^{\frac{1}{4}}$, where U is the velocity of the stream $\rho $ is the water density, $\alpha $ is the incidence of the sloping face and L is the lift on the wedge per unit beam. As the speed increases from zero, the immersion of the wedge increases to a maximum and becomes small at high speeds; the frictional drag increases to a maximum at the hump speed and falls to a constant value at high speeds.
